The resulting stabilized and shaped steel slag powder is named as "pretreated steel slag" in this paper. In addition, the specific heat of pretreated steel slag measured by TG-DSC simultaneous analyzer was similar to the data measured in the literature [ 3, 4 ].
When grinding slag cement, the amount of blast furnace slag can account for 20% to 85% of the total cement weight, which is very beneficial for improving the quality and reducing the production cost of cement.
With 10 wt% limestone addition, approximately 60% reduction in CO 2 emission and 21% in production cost can be achieved without compromising concrete strength. ... ground granulated blast furnace slag, limestone powder, and metakaolin in the hydration and durability of cement-based materials. Ultimately, their environmental and economic ...
However, their elevated production costs and substantial carbon dioxide emissions are not conducive to the principles of green, environmentally friendly, and sustainable development. ... While steel slag powder can effectively enhance the mechanical strength of soil and significantly reduce its water-induced swelling behavior ...
The system enhances safety by automating adjustments while minimising costs and environmental impacts. Data-driven strategies overcome the limitations of traditional methods, representing an advance for intelligent management of industrial processes. ... Wang K, Li X, Jia C, et al. Tracking control of slag powder production process based on ...
Using steel slag (SS) as cementitious material and fine aggregate in concrete is an effective and environmental method for SS consumption and cost reduction. In this paper, SS was recycled in large volumes in concrete as partial cementitious material and fine aggregate. The compressive strength and reaction mechanism of cementitious material with different SS …
One of the most well-developed technologies for minimising the GWP of concrete is to partially replace OPC with supplementary cementitious materials (SCMs) [6], [7], [8] such as fly ash, ground granulated blast furnace slag (GGBFS), waste glass powder, palm oil fuel ash [9] and limestone powder and calcinated clay [10], [11].In this study fly ash and GGBFS are used as …
